Assessment of the likelihood of pulmonary hypertension (PH) based on echocardiography according to ESC and ERS recommendations [5].

Parameter	low	Moderate		High
TRV	≤2.8 m/s	≤2.8 m/s	2.9–3.4 m/s	>3.4 m/s
TRPG	≤31.4 mmHg	≤31.4 mmHg	33.6–46 mmHg	>46 mmHg
PASP=RVSP	≤36 mmHg	≤36 mmHg	36–50 mmHg	>50 mmhg
other echocardiographic markers of
PH: evaluation of blood flow through the pulmonary valve; evaluation of overload and function of the right ventricle	absent	present	present or absent	present or absent

TRV – maximum velocity of tricuspid regurgitation; TRPG – the tricuspid regurtitation pique gradient; PASP – systolic pulmonary artery pressure; RVSP – systolic pressure in the right ventricle.
